Y

ln order to extinguish the light, the corl responding push rod 32 may bedepressed which in turn will d-epress the corresponding arm 28, or 29,and elevate the corresponding release rod 18, or 19, which will carrythe corresponding switch arm. 6 or 7 out of contact with the tongue 16and into the clamp 17 by which it will be held until its correspondingmagnet is again'energized.

Any number, or all, of the lights 2 and 3 may be illuminated eithersimultaneously, or

successively and they may be simultane-r ously extinguished bydepressing the push rods 32. Y

When the rods 82 are released the springs 30, 31 will operate to returnthe release rods 18,19 to their original or inactive position. Y c

Y l have shown and described which l now consider the preferredform ofthe apparatus, this showing, however, constituting only an illustrationof the principle of the invention. It is evident that mechanical changesmay be made and equivalents substituted for the parts shown and I herebyreserve the right to make such. structural changes or inodilications asmay be found desirable and as may be comprehended within the scope ofthe appended claims.

lVha-t I' claim is n 1. ln a signal device, a switch arm, pivotallymounted at one end, a pair of spaced switch tongues between which theswitch arm works, the free end of one tongue being overturned and formedinto a clamp adapted to engage and holdthe switch arm, a release rodarranged to actuate said arm into engaged relation with said clamp.

2. ln a signal device a switch comprising a pair of spaced parallelswitch tongues, a

switch arm, said arm being pivotally mountl ed at one end and adapted towork between the corresponding tongues of said pair, means operatableagainst said arm to carry said arm out oi" contact with one tongue ofAsaid pair the free end olf the other tongue Yhaving an arcuate, flexiblegrip forming inea-ns to engage and hold the switch arin out of saidcontact.
